Hi Carmen! Hard, dense bread can stem from a number of factors, such as flour measurement, liquid amounts in the recipe, how much the dough was kneaded, yeast health,  etc. Without knowing which exact recipe you made it can be a bit tricky to troubleshoot. We have a wonderful blog that gives some great tips for baking bread in a bread machine. I will link that right here: Successful Loaves from your Bread Machine
